FILTER.

SPECIFICATION forming part of Letters Patent No. 423,615, dated March 18, 1890.

r Application filed Augnstf), 1889. Serial No. 319,711- (No model.)

My invention relates to an improvement in filters, and has for its object to provide a filter of simple, durable, and economical 'con struction, capable of effectually extracting the impurities from water, and also capable of being attached to a faucet of any description.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the'accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure l is a central vertical section through one of the filter-tubes. tical section through the complete filter. Fig. 3 is apartial vertical section taken at a right angle to the section shown in Fig. 2. Fig. 4 is a plan view of one of the filter-tubes, and Fig. 5 is a section on line as w of Fig. 2.

I will first describe in detail one of the filter-tubes, as all of the said tubes are identical in construction, which consists of a body 10, tubular and preferably round, of any desired length, and of any suitable material. Near the bottom of the body, which is exteriorly threaded, as shown at 11 in Fig. 1, a preferably annular flange 12 is formed integral with the inner wall, upon which flange an apertured or perforated metal disk 1 3 is placed, which disk is of a diameter essentially equal to the inner diameter of the body and covered at the top, bottom, and sides with an asbestus cloth 14, which cloth is woven in such manner as to admit of the passage of water through the same under pressure. The interior of the body 10, above the bottom sieve or screen form ed by the disk and its covering, is partially filled with a clear sand 15, as illustrated in Fig. 1. Upon the top of the sand, which is packed down by hand as closely as possible, an apertured or perforated disk 16 is placed, which disk is also covered Fig. 2 is central verto prevent any water passing up in'contact p with the sides of thebody, which is liable to happen if covered metal disks only are employed. Above the cork disk two more disks 18 and 19 are placed, constructed in similar manner to the disk 16, and upon the upper disk 19 an uncovered metal perforated or apertured disk20 is placed. 7 series of disks is located is provided upon opposite sides with a lug 21, and the angular extremities of a bail 22 are made to contact with the said lugs, as shown in Fig. 1, which bail is provided at the center of its bow-section with a threaded aperture, adapted to receive a screw 23, the lower end of which screw contacts with the upper metal disk 20.

It will thus be observed that by manipulating the screw 23 sufficient pressure will be The end of the body in which the' exerted upon the series of disks below the screw to closely pack the sand in the body.

After the damp or wet sand has been com-,

and removed from the body and a fresh supply of dry sand 'is introduced in sufiicient quantity to fill the space gained by the last compression. The disks are now placed in position again within the body, the bail brought in contact therewith, and the screw made to bind firmly upon the upper disk and manipulated to further compress the body of sand.

Upon the eXteriorly-threaded end of the body 10 a cap 24 is screwed,from which cap a tube 25 is projected, preferably from a central point. o

A number of tubes constructed as above described are placed within a suitable jacket 26, as shown in Figs. 2, 3, and 5,which jacket is provided with a cap 27 at one end, and immediately beneath the cap a water-supply pipe 28 is projected transversely within the jacket, and the several tubes 25, radiating from the caps of the filtering-tubes, are connected with this supply-pipe, as shown in Figs. 2 and 5.

- Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. In a filter, the combination,with a tubular body having a screen or sieve firmly secured near one end, and a body of sand placed upon the said screen or sieve, of a series of screens or sieves and an interposed apertured corked disk placed in the opposite end of the body .'a bail attached to the body, and a screw carried by said bail, capable of contact with the outer disk to exert pressure thereon, substantially as shown and described. 7 v

2. In a filter, the combination, with a series' of tubular bodies having a screen or sieve firmly secured to one end, a body of sand placed upon the said screen or sieve, series ofscreen or sieves and an interposed cork disk placed in the opposite end of the body, a bail attached to the body, and a screw car ried by said ball, capable of contact with the outer disk to-exert pressure thereon, of a jacket open at one end and capped at the other surrounding the said series of tubes, a water-supply pipe projected within the capped end of the jacket, a cap covering one end of each tube, and branch pipes connecting each tube-cap with the supply-pipe, substantiallyas shown and described.

3. In a filter, the combination,with a tubular body having a screen or sieve held diametrically therein near one end, and provided with a packing or filling of sand which is supported by said disk, of a series of screens or sieves placed in the opposite end of the body above the sand, each consisting of a metal apertured or perforated disk and a covering of asbestus cloth, and'a cork disk closely fitting the interior of the body, introduced between the said series of disks, and means, substantially as shown and described, for exerting a continual pressure upon the outer disk of the series, substantially as and for the purpose specified.

4. In a filter, the combination, with a tubu lar body provided with a cap attached to one end, a screen diametrically supported within the'body a distance from the capped end, said screen consisting of an apertured metal disk having a covering of asbestus cloth, and

I a sand filling closely packed within the tube upon the said screen, of a series of screens with theuncapped end of the disk, and a screw carried by said bail contacting with the uncovered metal disk to exert pressure thereon, all combined for operation substantially as shown and described.
